 # perl-DateTime-TimeZone
 
+The DateTime::TimeZone modules provide a Perl interface to the Olson time zone database.
+Rather than using the database directly, we parse the database files and turn them into a set of modules, one for each time zone defined.
+This allows for various optimizations in doing time zone calculations.
+This conversion is done with the script in tools/parse_olson.
